Bi-directional engine control assembly

Abstract

Embodiments of the present invention relate to bidirectional rocker pedal assemblies that may be adapted for use in vehicular operations. In various embodiments, a subassembly may be coupled to a treadle and the vehicle to allow for bidirectional rotation of the treadle.

1 . A rocker pedal assembly, comprising
 A subassembly having an aperture passing there though and defining a rotational axis;   A shaft disposed in the aperture and further adapted to couple to a sensor;   A component having one or more shaft members projecting there from, wherein the one or more shaft members and subassembly coupled to the shaft to allow the subassembly and the component to move relative to each other, wherein movement of the component and/or the subassembly about the rotational axis causes rotational movement of the shaft; and   One or more biasing members disposed within and/or about the subassembly and adapted to act on the component to resist rotational movement of the shaft from a home position in both a first direction and a second direction.   
   
   
       2 . The rocker pedal assembly of  claim 1 , further comprising one or more loading members coupled to the component, wherein the one or more loading members engage the biasing member to help provide the rotational movement resistance. 
   
   
       3 . The rocker pedal assembly of  claim 2 , wherein the subassembly includes one or more receivers in which the one or more shaft members engage, the one or more receivers including stops adapted to engage one or more shaft member ends to limit the rotational movement of the subassembly or the component. 
   
   
       4 . The rocker pedal assembly of  claim 2 , wherein the biasing member includes a double torsion spring having a central portion disposed about the shaft and first and second ends extending in generally opposite directions from the central portion, and wherein the first end engages a first loading member and the second end engages a second loading member. 
   
   
       5 . The rocker pedal assembly of  claim 4 , wherein the subassembly further includes a first bias restrictor adapted to restrict movement of the first spring end in the first direction and a second bias restrictor adapted to restrict movement of the second spring end in the second direction. 
   
   
       6 . The rocker pedal assembly of  claim 2 , wherein the subassembly has a first surface having relieved edges adapted to allow for movement of the subassembly relative to the component. 
   
   
       7 . The rocker pedal assembly of  claim 2 , wherein the component is a treadle, a treadle support adapted to couple to the treadle, or a base member adapted to couple to a floor of a vehicle. 
   
   
       8 . A vehicle rocker pedal assembly, comprising
 A subassembly having a first surface having relieved edges and a second surface, the subassembly further comprising an aperture passing there though defining a rotational axis;   A shaft rotatably disposed in the aperture and further adapted to couple to a sensor;   A treadle support having one or more shaft members projecting there from, the one or more shaft members engaged with the shaft to allow the treadle support to move about the rotational axis and the subassembly to stay stationary, wherein movement of the treadle support about the rotational axis causes rotational movement of the shaft;   One or more biasing members disposed within and/or about the subassembly and adapted to act on the component to resist rotational movement of the shaft in a first direction and a second direction;   one or more loading members coupled to the treadle support, wherein the one or more loading members engage the one or more biasing member to help provide the rotational resistance; and   wherein the subassembly further includes bias limiters adapted to restrict movement of the treadle support in the first direction and/or the second direction.   
   
   
       9 . The rocker pedal assembly of  claim 8 , wherein the subassembly includes one or more receivers in which the one or more shaft members engage, the one or more receivers including stops adapted to engage one or more shaft member ends to limit the rotational movement of the subassembly or the component. 
   
   
       10 . The rocker pedal assembly of  claim 8 , wherein the treadle support is a treadle.
